Abstract
L'invention concerne un dispositif de signalisation de neige et de glace doté d'un ensemble détecteur (11) comprenant un capteur d'humidité (13) et un capteur de température ambiante (12). Un circuit d'évaluation, commandé en fonction d'une grandeur mesurée par le capteur d'humidité, émet pour des valeurs d'humidité déterminées un signal de commande pour dégivrer une surface surveillée en termes de neige et de glace. Le capteur de température ambiante (12) active le capteur d'humidité (13) dans les limites d'une plage de température comprise entre environ +2 DEG C et -12 DEG C. Le capteur d'humidité (13) possède un élément chauffant CPT dont la consommation est utilisée comme mesure de l'humidité. Le capteur de température ambiante (12) et le capteur d'humidité (13) sont placés, opposés l'un à l'autre, dans une cartouche (14) en plastique. Le capteur de température (12) est thermiquement découplé de l'élément chauffant CPT. L'élément chauffant CPT est logé dans une douille métallique protégée contre la corrosion et l'humidité.
